Description

Designed to provide stable system power and integrated backup functionality, the Beckhoff CX2100-0904 serves as a specialized power supply module for CX2020 and CX203x Embedded PCs. This unit features a capacitively integrated uninterruptible power supply (UPS) to protect systems against brief voltage drops and ensure orderly data preservation during power failures. Additionally, the module supports automatic recognition and power distribution to either E-bus or K-bus I/O terminals, facilitating seamless integration with Beckhoff EtherCAT and Bus Terminal setups.

The integrated, illuminated FSTN display on the front panel provides real-time status updates and diagnostics, enabling efficient local maintenance. Built with a robust housing and spring-loaded terminal connection technology, this module is optimized for industrial control cabinets where vibration resistance and high operational reliability are critical.

Features

Capacitively integrated UPS with 75 As capacity for safe state preservation and system shutdown.
Automatic bus system recognition for both K-bus and E-bus (EtherCAT) connections.
Supplies up to 2 A current to the connected E-bus or K-bus system terminals.
Illuminated FSTN text display (2 lines x 16 characters) for parameter configuration and system diagnostics.
Vibration-resistant electrical connection via reliable spring-loaded terminal technique.
Dedicated diagnostic LEDs for instant monitoring of Power, I/O Run, and I/O Error states.

Applications

Continuous monitoring and backup for PLC and industrial PC assemblies in factory automation.
Power management and terminal bus communication in process control environments.
Wind energy systems, packaging machines, and material handling systems requiring high-availability control architectures.
